Application filed July 95, 1918. Serial No. 781,109.

To all whom it may concern V Be it known that I, ALEXANDER CLAPPER- TON, a citizen of the United States of America, residing in Yonkers, in the count of Westchester and State of New York, ave invented certain new and useful Improvements in Protecting Devices for the Tubes of Pile-Fabric Looms, of which the following is a specification.

This invention relates to pile fabric looms used in the manufacture of Moquette and Axminster carpets, and has for its object to provide efficient means for the protect-ion of the end-tubes of the tube-frame so as to prevent them from being bent or placed out of position. It is well known that it is necessary to keep these tubes in exactly the correct position so as to prevent an interference in the operation of the machine, and a consequent stoppage thereof. But, on the other hand, it is also well known that when these frames with the tubes thereon are carried by the operatives from place to place in the factory and stored away for subsequent use, the end members meeting the thrust are subject to wear and tear and are bent out of position, which in turn bend their adj acent members out of position.

This invention consists in providing protecting devices for the tubes, whereby a novel device is produced comprisin the tube supporting frame, and a guardnger extending from the frame the length of the tubes alongside of the end-tubes.

In the accompanying drawing, Figure 1 shows a'plan view of a plurality of tubes attached to the frame and the improved guardfingers extending along the end-tubes for protectin the same. Fig. 2 is a side view of the embo iment shown in Fig. 1, and Fig. 3 is a vertical sect-ion on line 3-3 of Fig. 1.

Similar reference characters indicate cor responding parts throughout the several figures of the drawing.

Referring to the drawings, and more particularly to Fig. 1, a frame 10 is provided with a plurality of tubes 11 affixed thereto, the tubes 11 being arranged next to each other in closely adjacent position. These tubes are hollow throu hout their length so as to enable the thread: to be passed therethrough from the spool 20. It IS essential to have these tubes in exactly spaced position so as to enable the threads to always enter the tubes and not have the threads collide with the ends of the tubes and thereby bring about an interference or stoppage of the machine. For the purpose of protecting the end members, protectm devices are provided, each of which, 1n the embodiment shown in the figures, consists of a member one leg 12 of which is provided with holes through which screws 17 pass and enga e the frame 10, while the other leg 13 is at su stantially right angles thereto, and extends along the length of the end-tubes from their base to their free end, this 1 having a rectangular cross-section of su tantially the same size as the cross-section of one of the tubes, and extends to the tips of the tubes. The tip of the protecting end member is in the same plane as the tips of the tubes.

The protecting leg 13 at each end of the frame, as shown 1n Figs. 2 and 3 has its front or forward edge 14 and its lower corner 15 located forward of the plane of the front or top 16 of the tubes, and has its rear or upper corner 19 located a considerable distance beyond the rear or ingoing end 23 of the tubes. This construction prevents injury to the tubes in several ways. In case the tubeframe, when removed from the loom, be laid lengthwise on the floor, this can be done by laying the same with its front down, that is, the heads of the spool at 21 contact with the floor, and the rear-corners 19 of the guarddevices contact with the floor, and the tubes 11 are thereby supported out of contact with the floor on which they would otherwise rest at their ends 23. The tube-frame may be laid lengthwise inclined against a wall, with the lower corners 15 of the guards resting on the floor and the spool at 24 resting against the wall. In this case the weight is taken off the tubes which would otherwise receive the same, and by contact with the floor would be injured.

The rotecting-devices are independently removable from the frame without in any manner disturbing the tubes, and thus enable repairs to be easily made.

When it is desired to move the frame with its tubes from place to place in the factory, this protecting device serves to prevent the end-tubes from being bent out of their true position, as the protecting devices take up the thrusts.

I have shown one embodiment of my invention, but it is clear that changes may be made therein without departing from the spirit of the invention as defined in the appended claims.

I claim:

1. The combination, with the tube-frame and tubes of a ile-fabric 100m, of independently detacha 1e guard-members, secured one at each end 0 the series of tubes, in alinement therewith, said guard-members at their forward edges extending forward of the plane of the tubes.

2. The combination, with the tube-frame and tubes of a ile-fabric loom, of independently-detachab e guard-members, secured to the tube-frame, one at each end of the series of tubes, in alinement therewith, said guardmembers at their forward edges and lower corners extending forward of the plane of the tubes, and at their rear ends extending rearwardly of the enterin ends of the tubes. In testimony, that I c aim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
